[PATCH] next: input: Fix build error seen if input-core is built as module

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The following build error may be seen if input-core is built as module:

drivers/input/leds.o: In function `init_module':
leds.c:(.init.text+0x0): multiple definition of `init_module'
drivers/input/input.o:input.c:(.init.text+0x0): first defined here
drivers/input/leds.o: In function `cleanup_module':
leds.c:(.exit.text+0x0): multiple definition of `cleanup_module'
drivers/input/input.o:input.c:(.exit.text+0x0): first defined here
make[2]: *** [drivers/input/input-core.o] Error 1

leds.c is now part of input-core and can therefore not have its own
module initialization code. Initialize it from input.c instead.

Fixes: 6766fb48654c ("input: route kbd LEDs through the generic LEDs layer")

Problem is seen in linux-next and mmotm.

I am perfectly fine if the patch is merged into the original patch,
or if a different fix for the problem is implemented, as long as it
gets fixed.
